About this 1.21ct lab-grown asscher diamond

This 1.21ct lab-grown asscher sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG687529289 or 687529289. Listed at 2 retailers as of October 28, 2026, with prices from $670 to $870, a $200 spread on the same certified stone. Diamond Quarter lists it at $870. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
